TL;DR: This paper will present first attempt to extend the Meshless Local Petrov Galerkin method with Rankine source solution (MLPG_R) for studying violent water waves and their interaction with rigid structures, and proposes a near-strongly coupled and partitioned procedure to deal with coupling between violent waves and dynamics of structures.

TL;DR: Sriram et al. as discussed by the authors used the Fully Nonlinear Potential Theory (FNPT) solver to solve the Navier Stokes (NS) equation and applied it to a regular wave simulation.
Abstract: In recent years, our research group has been developing a meshfree method based on Meshless Local Petrov Galerkin Method using Rankin source function (MLPG_R) and recently improved the methodology for the smooth pressure evaluation (IMLPG_R), as reported in the previous ISOPE conference papers. As it is well known that the particle methods that solve Navier Stokes (NS) equation is time consuming when the waves propagate over a long tank or for a long simulation time. One way to overcome this is to couple the NS solver with the solver based on Fully Nonlinear Potential Theory (FNPT). In this paper, novel algorithms were employed to couple the FNPT solver (based on Finite Element method developed by Sriram et al., 2006) and NS solver (Sriram and Ma, 2010). The new coupled model has been applied to a regular wave simulation. The applications of the developed model for solitary wave overtopping and shallow water freak waves breaking are presented.
